<span> I. New species can outcompete native species to fill a niche.

Niche is like a profession because everybody in our world performs a different job. Niche is somewhat defines like what you do, how you do it, where you do it and when you do it.In ecology, a niche is a term about the relational position of every species like dolphin. In where dolphin can potentially be in another ecological niche by travelling from one place to another. Profession are something like finding your specialty, your place and your niche in the world.
Answer: Domain.
Explanation: I'm glad that you asked this question. When it comes to to biology and the identification of species, domain is the highest rank that you can find in taxonomy. If you look at the taxonomy ranks, this is the order: Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.
That is why domain includes all of the rest, because in the pyramid, it is the one at the top.
Answer:
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
Answer:
D. Porine
Explanation:
Mitochondria are double membrane-bound cell organelles. The outer and inner mitochondrial membranes are quite distinct from each other with respect to their structures and functions. The outer mitochondrial membrane is permeable to small molecules and ions. Permeability of the outer mitochondria membrane is mainly due to the presence of integral membrane protein porins which make transmembrane channels to allow the free movement of these substances across the outer membrane.
On the other hand, the inner membrane is quite impermeable to most small molecules and ions including protons as it does not have porins. A substance can cross the inner membrane only through specific transporters. The inner membrane has the components electron transport chain and the ATP synthase.
